About
A 0.8× focal reducer and field flattener optimised for a 102 mm f/7 objective, taking an f/7 refractor to f/5.6, and usable on other refractors of similar focal length. It slips into a 2-inch focuser and the camera threads onto the back. Stellarvue notes its performance depends directly on how accurate the telescope's own objective is.
